Specification of Letters Patent.

Patented March 1o, 1908.

Application `filed. May 16, 1907. Serial No. 373,907.

in Explosive-Engines; and we do hereby de-'v clare the following. to bc a full, clear, and' exact description oll the invention, suoli as will 1 0 enable others skilled in the art to which it appertains to make and use the same.-

Our invention `relates to explosive gas engines, has especial reference to the type of engine shown and described in the patent' l to John S. Lesch, No. 775,243, bearing date of Noveineber th, 1904'.

The invention haslfor its object economy in fuel and increased e'llectiveness in the operation of the engine, by the u se of kerosene, fuel oil of commerce, distinctively so known on the market, crude petroleum oil or dona* tured alcohol, or luel gas, as a substitute for gasolene or other light oil or distillate of petroleum. A further object is to obtain the maxii'nurn of power from the ehargeof fuel in a cylinder lof greatly reduced arca, as coi'npared with the present practice ol" constructing; and operating explosive gas engines. y f The invention .consists incertain improvemen-ts by which thel velocity olE the air supl l plied to the cylinder is aia-.elerated and the p temperature of the air increased in'traiisit, whereby thefuel oil is drawn into the gas and air mixing chamber andy is com niinuted and )ro entem ierature o'l'lhe exilosive mixf l ture and cool thewalls ol. theignition and combustion chambers when they become.

excessivelyheated, lo prevent preimiture ignition and explosion ol' the 'i'nixture ln the practical operation of engines in which coal oil, or `luel oil ol commerce is used, great di'lllculty has been encountered in getting su'llicient heat to vaporize the oil; and

to cil'ectthis extraneous means have been resorted to with some degree of success. lt is our purpose to vapoi'ize the oil by heat caused by friction produced by the air under pressure traveling through a contracted passage in the gas and air mixing chamber. e

followi'ig specification and claims:

lte'l'eience being had to thedrawing, and the designating characters thereon, the nus moral l indicates the ei'igin'e-cylinder, 2 adetaehable head Within which the. ex lesion of the. motor fluid is ell'ected; 3 the piston-rod; 4 the coiiiiei-.l.ing-rod; '5 the power Shaft; 6 the eccentric; 7 the eccentricvrod; and 8 an arm connected lo and reciprocated by the ln the accompanying drawings, which` tion o'li'the gas or vapor supply pipe, the gas A a vertical longitudinal section through the Fig.

The invention will be fully disclosed in thev being removed, and an elevation of part of l 9 of the electrical igniter (not shown). the governor, operated by a belt (not shown) eccentric-rod to operate the movable electrode 1 0 driven by the shaft 5 in the usual manner. The several parts described are of substantially the same construction as like parts in Patent #V77 5,243 and require no further elucidation.

On the side of the cylinder 1, and near the front end thereof is secured a chest 11 containing an air supply valve (not shown) Within the cylindrical portion 12, and whose stem 13 extends below the casingand within the chest above the air supply valve, is a governor valve (not shown) and which is connected to and operated by the rod 14 of the governor. Adjacent to the governor valve case 15, and in communication there- With through passage 16, is a gas and air mixing chamber 17 having a semi-cylindrical wall 17', and is provided with seats 18, 18, on Which rest rejections 19, 19 extending inward from t e cover 20, and from the cover projects a circular disk 21 Which is less in diameter than the circle described by the Wall 17 to leave a space or assage 22, as shown in Fig. 8, which is a most annular, between the wall .17 and the perimeter ot the disk. The disk contracts the chamber 17, transversely, causes the air coming from the air compressionY end of the engine cylinder and heated by compression to pass through the space or passage 22 at a greatly increased -`velocity Which produces a vacuum at the end of the distributor and operates to draw or suck the oil from the nipple 23 in the discharge end of the oil distributer 24, and at the same time increases the temperature of the air by the friction produced 1n the passage of the air around the disk 21, and vaporizes the oil, as will hereinafter more fully appear.

. The distributer 24 is secured to one of the projections 19, sec Fig. 12 and is provided with an oil passage which communicates with a passage 86, extends through the center of the distributer and to which oil is supplied through pipe 27, and channel 28, and the inner end oi the latter is controlled by a needle valve 29, to regulate the supply of oil from a reservoir, not shown.

29 indicates a ball valve resting on the end of the vertical passage 29.

30" is a passage communicating with the passage 26, and leads to a valve seat 81 controlled by a needle valve 32 secu red to an arm 83, and is provided with a head 34 which enters the chamber 85 above the valve seat 31 and guides the valve to its seat. (')il from vchamber flows through port 36, into the passage 25 in the oil distributor, from which it discharged through nipple 23. The end of the distributer is provided with a detachable cap 57 having a chamber 38, in which air is discharged from passages 39, .admitted through ports 40 and 41, and supplied through passage '42, extending through the disk 21 and supplied by the engine, through passage 16 leadmg from the governor valve case. f

The arm 38 is secured to a rod 43 on which is an arm 44 provided With a pin 45, which is engaged by a cam 46 on the lever 47 which is pivotally secured at 48 and is operated by an arm 49 secured to the governor valve stem 14, to supply oil in proportion to the load on the engine. The lever 47 is restored to its Anormal position by spring 50 when the load on the engine decreases, and the needle valve 32 is held to its seat, when no oil is required, by spring 51. The stem 52 of the needle valve 29 projects through the neck 52 on the cover 2() and is provided with a hand wheel 58 for manipulating the valve.

54 indicates the water supply valve provided with a conical seat 55, see Fig. 17, controlled by a like conical or needle point valve (not shown) having a stem 56 and hand Wheel 57.

58 indicates a water supply pipe from which a passage 59 leads to the Water chamber 79, and from said chamber the Water is conducted through port o r passage 60 in post 76 and travels through passages 61 and 62, and then through passages 63 and 64 into pipe 89, as shown in Figs. 2, 7, 8, 14 and 15.

The Water is controlled automatically by valve 7() on arm 71, connected to rod 72 and operated by the governor Lhrough the medium of arm 7 Sprovided with stud or pin 74 which engages the cam on the lever 47, and the valve 70 is held normally to its seat on the hollow post 76, by spring 77.

78 indicates a cap having a chamber 79 which incloses the post 76, and the arm 71, and forms a supplemental reservoir for water.

79 indicates the gas supply pipe leading from the gas mixing chamber 17 to the chest 8U, in which are the gas chamber 81, controlled by a valve 82, the ignition chamberlSB and the gas passage 84, leading to the head 2 of the engine cylinder, and extending through the cover 85 are the movable electrode 9 and the iixed electrode 86.

87 and 88 indicate thebindingpostsrespectively for the negative and positive wires to supply the electric current to the ignitcr.

0n the stem 82 of the gas valve 82 is a nut 90, on which spring 91 rests, for regulating the admission oi" gas to the engine.

89 indicates the pipe for conducting water to the gas chamber 81 and is discharged through the seat 92 oi" the valve 82, and enters the chamber 81 with the gas and passes on with it to the ignition chamber 88 and enters the working chamber oi' the engine in the head 2, and thereby cools said parts of the engine to such an extent as to prevent premature or accidental ignition and explosion of the gaseous mixture, and allows the engine to be worked up to its maximum ca acity.

93 indicates a water jackete lubricator cup connected to the water jacket of the engine cylinder bya pi e 94 to heat the lubricant and cause it to ow readily.

Durin the instroke of the piston, air admitted t rough the governor valve, fills the cylinder in front of the piston, and on the outstroke is transferred through the governor valve, the mixing chamber 17 and pipe 79 to the opposite end of the cylinder behind thepiston, the charge being compressed by the return stroke of the pistonv until the charge is ignited and the piston driven outward in the cylinder. The supply of air and oil or other-fuel is controlled by the governor, in quantities proportionate to the Work or load on the engi/ne, and the oil or fuel is ldelivered to the mixing chamber by the suction produced by the air in passing through the contracted portion of the mixing chamber, instead of being forced in, as is the usual practice, and is thoroughly commingled with the air from the outer end of the cylinder and forms a gaseous mixture.

When the load onthe engine is increased and more yfuel is re uired, water is admitted to the as and ignition chambers 81 and 83, controlled by the governor, to maintain the temperature 'at a point to prevent premature ignition of the char e.

The waste products o combustion are expelled from an exhaust port or passage, not shown, inflthe bottom of the cylinder..
